It's a two-wire light fixture without ground. When the switch is on I measure 120 volts between the hot and neutral in the ceiling fixture. If I switch it off I measure 50 volts. Why?

What are you using to measure this voltage? – ThreePhaseEel Mar 14 '21 at 15:50

1Sounds like phantom voltage to me, we have a couple of thousand questions on that. – Harper - Reinstate Monica Mar 14 '21 at 16:31

I am measuring in a ceiling fixture. On the actual wires. – brentonstrine Mar 14 '21 at 19:04

@brentonstrine -- no, I'm asking about the meter you're using to make that voltage measurement – ThreePhaseEel Mar 15 '21 at 00:11

Oh! Sorry. A multimeter. What else can you use to measure voltage? – brentonstrine Mar 15 '21 at 02:49

@brentonstrine -- does your multimeter have a Low-Z function on it? – ThreePhaseEel Mar 15 '21 at 23:56

I'll have to check. Looks like that function will help eliminate phantom voltage, which it seems is what I'm experiencing. – brentonstrine Mar 16 '21 at 04:13
